How your commercial property is assessed
If a property meets one or more of the following criteria, we assess it as a commercial property:
- Is used for retail, food service, office or other general commercial uses.
- Is a multi-purpose building that typically includes interior finishes, such as finished walls, flooring and lighting.
- Does not have a unique layout or specialized materials that would limit its use or functionality.
- Can usually be converted to another use without extensive alterations.
Factors affecting your commercial property value
Which factors we consider when assessing your commercial property value depends on whether we use the cost approach, the direct comparison approach, or the income approach.
